Detailed Description

Volume (cell) region selection class.

The adjustments for mesh changes have been implemented with a lazy evaluation, to avoid unnecessary recalculation until the values are actually required. The update() method is used to ensure the cache values are up-to-date.

Examples of function object specification:

volRegion0
{
    .
    .
    regionType      cellZone;
    name            c0;
    .
    .
}

volRegionAll
{
    .
    .
    regionType      all;
    .
    .
}

Usage

Property	Description	Required	Default
`regionType`	Selection type: all/cellSet/cellZone	no	all
`name`	Name of cellSet/cellZone if required	conditional
